摘要

竞技场地板上RC力矩框架的横向平面外响应损坏了一所学校体育馆，该体育馆本应用作自然灾害避难所。它由重型钢筋混凝土下部结构和轻钢屋顶组成，部分倒塌，导致该设施在2016年熊本地震中永久被毁。本研究描述了模拟2016年熊本地震期间学校体育馆RC力矩框架平面外响应损伤的比例振动台试验，并验证了先前数值模拟提出的损伤机制和摩擦阻尼器支撑的响应控制效率。此外，该研究验证了两种评估RC弯矩框架响应和具有半刚性节点的屋顶特拉斯构件整体屈曲强度的方法。

Scaled Shaking Table Tests Simulating the Damage of the School Gymnasium in the 2016 Kumamoto Earthquake

The transverse out-of-plane response of the RC moment frame on the arena floor damaged a school gymnasium that was expected to function as a natural disaster shelter. It was composed of heavy RC substructure and a light steel roof, which partially collapsed, resulting in the facility's permanent destruction in the 2016 Kumamoto earthquake. This study describes scaled shaking table tests that simulate out-of-plane response-induced damage to the RC moment frame of the school gymnasium during the 2016 Kumamoto earthquake and verifies the damage mechanism proposed by the previous numerical simulation and the efficiency of a response control by the friction damper support. Furthermore, the study validates two methods for evaluating the response of the RC moment frame and the overall buckling strength of the roof truss member with semi-rigid joints.
